Subject: [PATCH] Fix automatic marking of constraints as reference.

To reproduce:
  * New sketch;
  * Create two redundant constraints, with second being automatically
    marked as reference;
  * Switch one of these to non-reference;
  * Allow redundant constraints;
  * All new constraints with labels created as reference, even
    if that specific degree of freedom is not constrained yet.
